MACHINE FOR DELlNTlNG COTTON-SEED.

SPECIFICATION forming part of Letters Patent No. 430,843, dated June 24,1890.

Application filed December 2 8, 1 8 89.

To all whom it may concern:

Be it known that I, JAMES J ONES FAULK- NER, a citizen of the UnitedStates, an d a resident of Jackson, in the county of Jackson and Stateof- Michigan, have invented certain new and useful Improvements inMachines for Delinting OottonSeed, of which the following is aspecification.

My invention relates to machines for removing the lint fromcotton-seeds. Its obj cot is to rapidly remove the lint without breakinthe kernels.

The invention will be first fully described in connection with theaccompanying drawings, and will then be particularly pointed out in theclaims.

In the accompanying drawings, in which like parts are indicated bysimilar referenceletters wherever they occur throughout the differentviews, Figure 1 is a central transverse vertical section of a machineconstructed according to my invention. Fig. 2 is a front elevation ofthe same upon a reduced scale, having a portion of the casing brokenaway through line a: m of Fig. l to expose the parts back of it; Fig. 3,a detail view in end elevation upon the same scale as Fig. 1, thesprocket-wheels being cut off by a section taken vertically throughtheir shafts. Fig. 4 is a detailed view upon an enlarged scale of partof the cylinder and the check-plate, showing means for adjusting thelatter vertically. Fig. 5 is a detailed View upon an enlarged scale of aportion of one of the feedrolls perforated to receive the feed-pins.

The cylinder A is secured upon a shaft 13,

which has its bearings in the supporting up- I rights or end standards0. The exterior of the cylinder is, for lightness, preferably formed ofwooden staves a, which are secured upon the rim of the armed wheels orspiders a, keyed upon the shaft B. The surface of the cylinder A iscovered with sand-paper, emery or card cloth, sand, concrete, or similarrough or scouring material 0L2, to which the lint will adhere.Thecylinder is inclosed in an outer shell formed by wooden end pieces Dand a sheet-metal cover fasten ed around their edges;

the machine and carried into contact with the surface of cylinder A by aseries of feedrolls E. The shafts e of these rolls have their bearingsin flanged metal hubs e, which are secured to the ends of the chamber Dby screws passing through their flanges. Upon the projecting ends ofthese shafts are se cured sprocket-wheels 6 A similar wheel Z) issecured upon the cylinder-shaft B. The feed-rolls are all driven in thesame direction by a sprocket-chain F, which passes around the wheels Z)6 The tension of the sprocketchain is regulated by an idle-sprocket 0",carried by an arm 6", which is pivoted upon a stud-bolt secured in theend of the case, as shown in dotted lines in Fig. 1.

The feed-rolls are provided with pins which are preferably arranged uponspiral lines to carry the seed from the feed to the discharge end of thechamber D. is a grated opening, as seen at (7 Fig. 2, at the end of thechamber diagonally opposite from the feed, the interstices of thegrating being just large-enough to permit the seeds to pass after theyare freed from lint and from one another, as they will be when the lintis removed.

The upper end of the chamber D is pro vided with a check-plate I, whichispreferably made vertically adjustable, as by having its securing-b0ltsI pass through slots I therein, as in Fig. 4. Its lower edge is set asuffieient distance from the cylinder to allow the lint from the seed tobe carried around 011 the The brush-shaft g The seeddischarge driven bya band which passes over a pulley 5 secured upon the end of thecylindershaft B.

The chamber D, is for convenience, made separate from thecylinder-casing and hinged to it at II, so that by throwing off thesprocket. chain F and disengaging the fastening-hook 7b the chamber,with its feed-rolls, may be turned down for the purpose of replacing thesandpaper or other scouring material used upon the cylinder when itbecomes worn.

The operation of the machine is as follows: Seed, being fed into thechamber D, is carried by the toothed rolls to the scouring-sun face ofcylinder A. The tendency of the feedrolls is to carry the seed downtoward the bottom of the chamber D, while the tendency of the cylinder Ais to carry them in the opposite direction. So long as any lint adheresto the seed they hang together, so that the teeth of the feed-rolls willhold on to them and continuously at each revolution bring them incontact with the rough strippingsurface of the cylinder; but so soon asthe lint is removed they will be released from the teeth of the rollsand will not adhere to the cylinder, but drop by gravity to the bottomof the chamber D and be discharged through the grated discharge-opening.

I have shown and described What I believe to be the best form of myinvention; but 1 do not limit myself to the exact forms shown, as manystructural changes will readily occur to those skilled in this branch ofthe art. I shall therefore consider such mere mechanical modificationsas Within the spirit and scope of my invention as herein claimed.

I claim 1. The combination of the supporting-frame, the cylinder havingits surface coated with sand-paper or similar material mounted torevolve therein, the outer casing inclosing said cylinder and having thefeed-roll chamber D, the toothed roll fitted to revolve in said chamber,the check-plate to prevent the seed being carried to the lint-dischargechamber, the revolving brush to strip the lint from the cylinder anddischarge it from the machine, and means for driving the cylinder,brush, and feed-rolls, substantially as shown and described.

2. The combination of the cylinder A, having the surface-coating a thecase inclosing said cylinder, the chamber-D, having hopper d and grateddischarge (1 hinged to one side of said casing, the lint-dischargechamber D at the opposite side, the feed-rolls E, mounted to revolve inchamber D, the brush-cylinder Gin the lint-discharge chamber, and theplate I to prevent the seed from passing to the lint discharge chamber,substantially as shown and described.

3. The combination, substantially as described, of the supporting-frame,the lintingcylinder, the case inclosing the same, the lint-dischargechamber at one side of said case and the feed-chamber at the oppositeside provided with a hopper and seed-discharge chamber, the feed-rollsmounted to revolve in the feed-chamber in proximity to each other and tothe cylinder, the feed-roll shaft extending outside of said chamber, thesprocket-Wheels secured upon said shafts, the sprocket on thecylinder-shaft and sprocketchain F for driving the feed-rolls, thebrushes in the lint-discharge chamber, the brush-shaft g, pulley g,pulley Z) on the cylinder-shaft,

and the belt to drive-the brush.
